Hybrid Schrödinger-Feynman Simulation of Quantum Circuits with Decision Diagrams
No full textKlassische Simulation von Quantenalgorithmen und -schaltungen ist ein we-sentlicher Bestandteil in der Entwicklung von Quantum Computation im Ge-nerellen. Zur Durchführung der Simulation sind die verschiedensten Metho-den vorhanden, darunter auch die Benutzung sogenannter Decision Diagrams.Diese erlauben die exponentielle Komplexität dieser Simulationen durch dieAusnutzung von Redundanzen in den Quantenzuständen zu adressieren. Nichts-destotrotz, leidet auch die Simulation mit Decision Diagrams an der exponen-tiellen Komplexität, vor allem dann, wenn die Quantenzustände keine Redun-danzen beinhalten. Darüber hinaus nutzen die meisten Simulationsmethodendie verfügbaren Hardware Cluster durch eine massive Parallelisierung der Si-mulation. Dies ist allerdings, mit aktuellem Stand, nicht in derselben effizien-ten Weise mit Decision Diagrams umsetzbar.
Diese Thesis wird zeigen, dass beide Probleme mithilfe einer Simulationstra-tegie, der sogenannten hybrid-Schrödinger-Feynman Methode, adressiert wer-den können. Des Weiteren werden die Details dieser Lösung für Decision Dia-grams, verschiedene Optimierungen und die resultierenden Probleme beschrie-ben und adressiert.
Am Ende werden in einer empirischen Evaluation die positiven Auswirkun-gen dieser Strategie gezeigt, das führt soweit, dass manche Simulation inner-halb von Minuten abgeschlossen werden können, die aktuelle Ansätze mit De-cision Diagrams nicht innerhalb eines Tages abschließen können.The classical simulation of quantum algorithms and circuits plays a significantrole in the development of quantum computation. There are different simulation strategies available which also include the usage of decision diagrams.They have been proposed since they allow to address the exponential com-plexity of the simulation of quantum circuits by exploiting the redundancy inquantum states.
However, they still suffer from two major obstacles. First, they cannot over-come the exponential complexity when the underlying quantum states do notcontain redundancy. Second, while many other techniques exploit the hard-ware clusters that are available today by executing the simulation in a mas-sively parallel fashion, decision diagrams do not profit by the same amountfrom those resources since they cannot be efficiently parallelized yet.
This thesis hows thath of those obstacles can be addressed by employinga hybrid Schrödinger-Feynman approach. It discusses the details of the real-ization with decision diagrams, how the approach can be improved using dif-ferent optimization strategies, and how the arising problems can be addressed.
At the end, experimental evaluations confirm that this strategy has a majorimpact on the simulation performance, even allowing to simulate certain in-stances within minutes that could not be simulated within a whole day usingthe state of the art.submitted by Hartwig Bauer, BScMasterarbeit Universität Linz 202
The status of Aboriginal water holdings in the Murray-Darling Basin
No full textThis report presents the findings of a data benchmarking exercise commissioned by the Murray-Darling Basin Authority (MDBA). The report intends to improve understanding of current Aboriginal surface water and groundwater access and basic demographic data across current water management units in the Murray-Darling Basin (MDB). The MDBA commissioned this work following similar research that the lead author completed as part of her PhD at Griffith University (Hartwig, 2020). That work examined Aboriginal water entitlements for only the NSW portion of the MDB (see also Hartwig, Jackson & Osborne, 2020). The specific tasks of this project were to: • Update (2016) Aboriginal population statistics for all regions across the Basin, based on Surface Water Sustainable Diversion Limit (SDL) resource units; • Establish a Basin-wide 2020 Aboriginal water holdings baseline/s that is compatible with Basin Plan water accounting methods; • Where possible, document changes to Aboriginal water holdings over the last 10 years; • Identify features of entitlement and licencing systems and recordkeeping that limit future monitoring of Aboriginal water holdings; and, • Develop recommendations for the MDBA and the Basin States and Territories to improve monitoring of water access for Aboriginal peoples and inform future research. The information contained in this report will be useful to policy-makers and officials from the MDBA, the Indigenous Land & Sea Corporation (ILSC), New South Wales Aboriginal Land Council (NSWALC), and various state and federal government agencies. It will also be of use to Basin Aboriginal peoples and their representative organisations, including (but not limited to) the Murray Lower Darling Rivers Indigenous Nations (MLDRIN) and Northern Basin Aboriginal Nations (NBAN). More specifically, these baselines will be of crucial importance to current government efforts to develop new policies and programs targeted at improving Aboriginal water access in line with national water policy; evaluate and monitor existing plans and programs (including the Basin Plan); and, assist First Nations people to contribute to water policy. It also complements the recent assessment of social and economic conditions in the MDB (Sefton et al., 2020).Full Tex

American Translations of Julia Hartwig. Peryphery and Paraphernalia
No full textThe author discusses a new feature, which develops in Julia Hartwig’s poetry after her several visits to the States in the years 1970-1974 and her immediate introduction to the American verse - through reading and translating. In Hartwig’s poetry, new mundane lyrical situations appear and her verse becomes much more concrete, but also voyeuristic. Some analyses of excerpts from her Dziennik amerykański [American Diary] and Wiersze amerykańskie [Americana] are provided, as well as of The Young Housewife by William Carlos Williams in Polish translations done by Hartwig, Piotr Sommer, and Stanisław Barańczak.Autorka opisuje nowy rys, który pojawił się w liryce Julii Hartwig po tym, jak począwszy od lat 70. XX wieku, odbyła kilka dłuższych i krótszych wizyt w Stanach Zjednoczonych, gdzie zaczęła czytać i tłumaczyć poezję amerykańską. W poezji Hartwig pojawiły się nowe, bardziej przyziemne sytuacje liryczne, a sama poezja stała się bardziej nasycona konkretem, choć także voyeurystyczna. W artykule zostają przywołane i zinterpretowane wyimki z Dziennika amerykańskiego oraz Wierszy amerykańskich Hartwig, a także liryk Williama Carlosa Williamsa The Young Housewife w oryginale i przekładach Hartwig, Piotra Sommera i Stanisława Barańczaka
Sztuka zamieszkiwania - o wierszu "Drzewo to dom" Julii Hartwig
No full textThe article is an analysis the poem by Julia Hartwig Drzewo to dom. The text from the
book of poetry Zobaczone is real by the author as an expression of a deep need of a “double
rooting” in a spiritual, metaphysical as well as earthly, physical sense, but also as a poetical
reflection on the art of living in oneself, in one’s psychophysical separation, in the
culture, and, among others, in the community of a “human family”
"Žena je jedno ništa" Mele Hartwig. Feminizam u književnom narativu postimperijalnog naslijeđa
No full textThe Austrian writer Mela Hartwig (1893–1967) interprets the reality of women in the post-imperial period and shows the consequences of misogynist theories for the construction of feminine identity. In the short story „Das Verbrechen“ („The Crime“), the author describes the psychopathological relationship between the father and the daughter through a cruel „play“ motivated by Freud's theory of psychoanalysis. In the novel Das Weib ist ein Nichts (The Woman is a Nothing), Hartwig deals with the constellation of institutional and extra-institutional power. The writer chooses a very radical, unusual and provocative form of analysis and criticism to show a dominant masculine culture. In her literary discourse, the "new woman" of the liberal 1920s is cast as a myth since Hartwig does not show optimism about upcoming changes in gender relations
Marx's reproduction schemes and the Keynesian multiplier: a reply to Sardoni
No full textIn a recent contribution to this journal, C. Sardoni takes issue with the identification by Trigg, in a 2006 publication, of a role for the Keynesian investment multiplier in Marx's schemes of reproduction. Indirectly, Sardoni also expresses his disagreement with Hartwig (by attributing one of his statements to Trigg). We appreciate the opportunity to defend our view against Sardoni's critique. This reply shows that a bridging point between Marx and Keynes can be established without recourse to microfoundations. As suggested by both Trigg, in 2006, and Hartwig, in 2004, the well known Harrod--Domar model of economic growth provides an interpretation of Marx's reproduction schemes that has the Keynesian multiplier as a constituent element. This note will further explore the assumptions underlying the interface between Marx and Keynes, in response to the challenging questions raised in Sardoni's contribution. Copyright The Author 2010.

Doświadczenie i "przygoda życia" w książce "Gerard de Nerval" Julii Hartwig
No full textThe article presents an interpretation of the book entitled Gérard de Nerval. The author,
paying attention to this slightly forgotten book, remaining in the background of other
works by Julia Hartwig, notices there not only a book on the French poet, but also
a record of experiencing a book and text that can also be read in the autobiographic
context
Fotografie z pamięci. O powrotach w przeszłość w poezji Julii Hartwig
No full textThe author of the article reflects on the category of memory in poetry by Julia Hartwig who constitutes the identity of the lyrical subject through a constant reference to the past. The motive of eyesight and photography, as noticed in frames, overlaps with the idea of repetition, being memory’s work against emptiness. The reality of the history, uncovered and turned inside out by a poetical „I”, combines with a dreamy vision and sub-consciousness many times. The role of memory turns out to be two-fold; a destructive and sense-illuminating one, including the element of distance and sublime. Distance in the light of memory demythologizes it, exposing „infidelity” in the light of what it has been entrusted with. Miłosz’s conception of testimony as a proof of existence appears important for considerations on memory in poetry by Hartwig. When confronted with a desire to retain things in a whole image, the awareness of emptying memory is consolidated by a dramatic nature of the attitude visible in works by the author of Czułość.The author of the article reflects on the category of memory in poetry by Julia Hartwig who constitutes the identity of the lyrical subject through a constant reference to the past.
